JOHN O. RICHMOND, OF SPRINGFIELD, OREGON.

COMBINED HARROW AND WEEDER.

Specification of Letters Patent.

Application filed August 4, 1908.

To all whom it may concern:

Be itknown that I, JOHN O. RICHMOND, a citizen of the United States,residing at Springfield, in the county of Lane and State of Oregon, haveinvented certain new and useful Improvements in Combined Harrows andfeeders; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in combinedharrows and weeders and it is an object ofthe invention to provide adevice of this character which is of the drag type and so assembled asto permit a rotary movement of the weeder and the harrow, the rotarymovement of the weeder and the harrow being independent one of theother.

It is also an object of the invention to provide a novel device of thischaracter wherein the weeder is so constructed as to draw the weeds fromthe ground or soil in lieu of the well known idea of cutting the weeds.

It is also an object of the invention to provide a novel device of thischaracter which will be simple in construction, efficient andadvantageous in practice and comparatively inexpensive to manufacture.

IVith the above and other objects in view, the invention consists of thedetails of construction and in the novel arrangement and combination ofparts to be hereinafter more particularly referred to.

In describing the invention in detail reference will be had to theaccompanying drawings forming parts of this specification wherein likecharacters of reference denote corresponding parts in the several views,and in which,

Figure 1 is a top plan view of the invention, and, Fig. 2 is a sectionalview taken on the line 22 of Fig. 1.

In the drawings 1, 1, denote two cross beams, arranged at right anglesone to the other and having secured to their under surface at the outerend portions the depending knees, 2, which are secured by suitablefastenings, 3, to a ring 4. This ring 4 has its outer upper portioninclined to form cutting edges 6, said inclination making the ringapproximately semi-oval in cross sections. It has been found that thesecutting edges are most essential as when the ring 4 is moved it willplow its way in the soil or ground and work under the surface thereof toa depth of two or three inches and thus remove the weeds from theground, and not cut the weeds at the ground, an advantage, which isthought to be obvious.

Passing through the beams 1 at their in tersection there is a rod 7,which also passes through the frame 8 of a circular harrow 9.

This rod is provided at its lower end with a head 10, which is confinedwithin a housing 11, secured to an under surface of the frame 8. Theharrow is adapted to rotate around the rod 7 and the head 10 is employedto retain the harrow, or its frame 8 on the rod and to permit anelevation of the harrow when desired. The rod 7 projects a desireddistance above the beams 1 and has secured to the upper end thereofthrough the medium of the bolts 13, the downwardly and outwardlyinclined parallel rods 14 which have their lower end portions 15contacting and provided with a plurality of openings 16 for the properengagement of suitable draft rigging, not shown.

In order that the harrow 9 may be elevated, the rod 7 intermediate itslength has clamped thereto, the two parallel bars 19, the outer ends ofsaid handles being pivotally secured by the pin 20 between the rods 14.To the outer end portions of the parallel bars 19 are secured theoperating handles 22, which are suitably held in position by theirbraces 21.

In order to enhance the operation of the device there is mounted betweenthe lower ends of the rods 14 beneath the openings 16 the wheel 17 Inorder to elevate the harrow out of use, it is only necessary to suitablymanipulate the handles 22 so as to poise or pivot the machine upon thewheel 17, when it is apparent the harrow may be moved about the fieldfrom place to place as required, and when brought to rest as foreffective use, the hand pressure is simply removed from the handles whenthe harrow teeth will be lowered into contact with the ground.

I claim:

A device of the character described, comprising crossing beam membersand an up-' right central rod member passing through said crossing beammembers and having its In testimony whereof I have signed my lower endsupported in position, an annular name to this specification in thepresence of member substantially oval in cross section two subscribingwltnesses.

with its lower edges adapted to cut into the JOHN O. RICHMOND. surfaceand depending knees between said Witnesses: crossing beam members andsaid annular JOSEPH J. BRYAN,
